Resource guide: Level leverage

Feb. 11, 2019
Control's monthly guide brings you invaluable industry information to stay up to date on the latest trends and developments.

Basic types education 

The 10-minute video, "Process control basics: level measurement," is presented by Control editor-in-chief Paul Studebaker, and is part of its Educational Video Series. It covers the difficulties of sensing levels, application issues, advantages and disadvantages of common technologies, such as mechanical, magnetostrictive, capacitance/RF admittance, ultrasonic, differential pressure, radar and guided wave radar, laser level, nuclear, radar and other methods.


12 Ways to measure fluids

This online article, "A dozen ways to measure fluid level," details all the essential level measurement methods, their history, how they've evolved, and more recent innovations. The three main categories include established, hydrostatic and modern technologies.


Introduction and selection

This online article, "Introduction to level measurement," covers float switches, non-contact and contact ultrasonic and capacitance technologies; offers links to applications including storage tanks, cooling towers and life sciences; and gives a list of questions users should answer to pick the right level measurement device.
